To all tollem it may concern.'

it known that l, Mismas L. S'mxn, of Iawell, in the county of Middlesex and State of Massachusetts, have invented cci;- tain new and useful Improvements m Anti matic wefblieplenishin Looms. of which the following is a speci cation.

The preaent invention is an improvement upon t at act forth in United States Letters l atent No. 02l,ll09, May 18, 1000. and it relatea more articularly to the devices employed for olding the threads of weft-carriers during their occupancy of a maga-ine and prior tu their automatic transfer to the shuttle of the loom when the replenishment of weft is required. In said patent there is described a weft-carrier having a detachable weft-end holder which remains on the weft #carrier during its oeeupane of the magazine and until just prior to tie transfer of the weft -carrier to the shuttle, whereupon automatic mechanism removes the weft-end or thread holder still holding on to the thread so that the thread is hehl dur- .ing the transfer of the. weft-carrier to the' shuttle and during the first llight of the shuttle through the shed. This prior construction has involved the employment of uiekly acting motor mechanismto remove t ie detachable weft pomibility ol' the breakage. of the thread as .the result ofthe wmoval ot the weft-holder.

The primary object of the present invention is to provide n ditl'erent arran rement for taking care of the weft-ends or t treads. In accordance with the pmwnt invention there is provided a separate weftend holder for each bobbin or other weft-carrier, hat the weft-end holder is never conn'e'ctcd direetly to its weft-carrier but traverses its own guideway cmieurwntly with the movement of the weft-carrier prior to its transfer to the loom. 'I`he-1e lseparately guided iurlividual weft-end holders are governed by i aim le nomment mcehaninm"which in ae- Luat whenever u transfer is made of a weft-carrier from the magazine to the lhuttle. In connection with the improved manner if taking care ofthe. erft-ends there are ilno` other features of improvenn-nt. "he mproved weft-end holders are preferabiy ined in connection with a detachable maga- :ine which can be lillcd with weft-carriers lpart from tho loom and can be scoured to -eud holder and nlm the the loom when desired. In connection with such n detachable ma azinc there is cmployed a concurrently tetacbable guide for the individm l weft-end holders.

An embodiment of thapresent improvements is illustrated :in the accompanying drawings in whirhv ItI 'ure-Pis .a `idc view of the improved nmgazrne and act't-end holders, with so much of the usual mechanism of a weft-replenishingg loom as will enable the improvements to e readily understood. Fig. 2 is a plan view. Fig. 3 i# a front view of the detachable part of the vma nzine, together witli the upper portion o the permanent part of the magazine. Fig. 4 is u. vertical section in the plane indicated by the line 4-4 in Fig. 2. Fig. 5 is a detail view of the mechanism for eontrollin the action ot' the wett-end holders. Figf is a vertical section of a portion of the detachable magazine. Fi v. t is a vertical section in the plane im icated by the line 7--7 in "i 2l of the meeting ends of the detachable and permanent portions of the ma ezine. Figs.

'lbe nm zine ctmsists of a stationary chute A smtnbl secured to the aide of the loom and over `.anging the shuttle-box at one end of the lay when the lay is forward. 'l`he lay in its forward position is shown at a in Fig. 4, and the wsition of the shuttle l thereon is indicated at. the time when a wett-carrier c is being transferred thereto. 'lhe detachable magazine is shown at B. 'l'he fixed chute A has an open socket at. ita

guideway top, ns indicated in Fig. 7, into which the lower end of the detachable magazine Il may be inserted and tilted, rating therein b' gravity. lrior to putting the detachahe magazine in place its open bottom is closed bv a removable slide d. lVhen the detachn le ma 'ir/.ine is in place, this slide is removed t trou h o suitable opening c in the front wall oli: the lixed chute (see Figs. 3 and 7) and is then placed in a suitable pocket f (sec Fig. 3) on the detachable magazine where it is ready for future use. 'lhc fixet chute and the detachable ma zine, when in place, furnish a continuous c annel for the t always detached studs in front.

weft-carriers e and they may bc of any desired height to receive am' convenient number of weft carriers. l` he weft-carriers descend b v gravity and the butt ends. are guided in :i known wayliy inwardly projecting rilis y, y, witli which the lixeil rli-utu und detachable magazine are equipped. The

stark of \\'eft-ea:riers'is supportvl in the' when the-comlition of the weft in the shuttle llie traiisferrer is restored to its v demands. noruial` upliited position by the usual sprin 'lhere is a weft-end holder I) for eii'eliY weft carrier but each weft-cial holder is from its corresponding weft -earrien 'lhe weftend holder' is con: structed to tit over and slide upon a guide E. as clearly shown in Fig. l0. Each weft end holder has an appropriate forwardly projecting stud l` on which the weft-end clon ing to its weft -ciirrier is wound (neey Fig. and it also has a laterally projecting lng (l which eo|arates with thesra ment mechanism. ln cime the tlirciid slut becomes filled with thread, the thread can be readily removed by cutting it. a slot lA being provii ed in ne thread stud F for the insertion of a knife. 'lhc wef-end holders I) Ii: loom-lv on the guide E so that they can readily slide down the san'ie by gravity. The guide extends parallel with thc ma nizine and tixed chute, and at its lower end tiere is secured toit an open-mouthed funnel H which conveys tli'e spent' weft-end holders to -a suitable receptacle. The guide comprises a rib m and a track n, the track being circular in croamiection (see Fig. l0) to receive the weft-end hol lern. The rib m revenni the rotation-e! lhewa'ett-.ead hot en. Ila-rch maintainin them with their thread *he {anne} H is secured lo the lower end of the rib m, while the lower end of the track n tenninateirwithin the open mouth of the funnel so that .the weft end holders aa they leave the track fall into theV funnel and are suitable receiver.

The weft-end holder guide is in {w-o .sectionii. the lower section bein one and atiitably secured to. t e xed chute .Yihroagh the txedbrucket I. The up er section of the guide is adjustably secu thereby directed tu any lirnontiil slide AJ (as 'shown in Figs. 3 and by the lowerinost weft-carf lly (as shown in Fig. l) to*y a atationiu'yv to' -the detaelinhlo uuigazine `by A means of the' Vupper sectionof t e'guide E po-ition "shown in dotted lines yward withdrawal of the sli( thread from all of thc weft-carrienito'the When the iuiwiiziiige B is detached, the

When theu'ipper portion of the guide is in` this position the weft-carriers are placed oneb 'one into the open top of the detachable magazine. and corresponding weft -end holders are placed upon thel guide E, and as each weft-,carrier is placed in position the end of its thread is wound around ththread stud Aof the cnrrespondin weft-end holder. During this time the we t-eiid` holders are maintained on the movable part of the guide iiy means -of the pivoted ies vthe position shown in dotted lines in Fig. 9.

guide E is filled with weft-end holdem thev sinne a re transferred to the looni and the detachable magazine is set. in place within the socket on top of the-fixed guide chute A. The slide J is then moved outwardly to the position shown ir. full lines in Fig. -3', when it is secured in ilaee by the spring'bolt K entering a secoin hole (similar to the hole o.) inthe slide, as' indicated in 8.

The normal position tent is shown in Fi stop N -is then in the aaperlm by aneaca path ofthe lug (l i :the

loweruioat weft-end holder. 'At thiatime th'e free end ofthe detont P is not in line with the lugs (l of the weft-end holdem, as 'wilt be clearly evident from Figs. t and @im causo, as shown in Fig. 2. the free cnil of the detcnt is turned inwardly, and. as `shown in o! the stop and the de. g. 1. As there shown the.

ius

ise'* Fig. l, this inturned end terminates well in front of the path of the lugs (i. The rock shaft Q at its inner end has a crank arm R which at its forward end has a slotted eonnection (shown iu Fig. t) with au arm S Secured to the transfcrrer C. As a consequence, when the transfernu' moves downwardly to transfer a weftearrier, the stop .\I and detenta P are coneurwntly swung to the position -ahown in Fig. As here shown. the stop is swung downwardly and rearwardly out of the path of the lugs on the weft-end holders. thus permitting the lowermost weft-end holder to drop into the open mouth of the funnel ll. .-\t the same tune the superimposed. stack of weft-end holders drops down 'by gravity, but they do not escape because the dctent P is then in position to stop their descent. When thc trans- 'ferrer C again rises to its initial position. the stop and detent also risc, thereby moring the detent P out of 'the way again. hat bringing the stop N first into the path of the luga (i so that the furtherdeacent of the weftend holders after aiming the detent is prevented hy the stop. his atlords a ready, convenient and sim le mechanism for feeding the weft-end holders one by one concurrently with the feeding of the` \\'ettearrieru. tlieaamc bein under the control o! the tranaferrer andl hence under the control of the devices which indicate the exhaustion, breakage. or approaching exluulstion, ot the shuttlq' tread in use.

It ia` esirable that, in the tirst instance,

`the lowermoat weft-end holder should not have a thread attaehcd to it, so that the hottom weft-carri@ hall have its front attached to the weft-end holder next above the lowest one. 'lhe reason for this is that the lowermust weftend hohlcr is dropped into the funnel eonoiirrently with the first traverse through the shed of the freshly inserted u'eftrarrier, and it is desirable that the weft-end holder then holding on to the end of the thread should be itself stationary. Accordingly, in tirst placing the weft-end holders upon the guide the lowermost holder will have no thread attached to it.

During.: the action of the transferrer the stock of weft-end holders is supported in a known manner h v means of a retainer on the transfert-er, as shown in Fig. 4. 'lhere is a continuous slot t in the outer wall of thc chute A and magazine li. respectively, (sco lfigs. 1 and 2) through which the \\'oftcmls extend from the weft-carriers c to the weftend holders D. This improved method ot' taking care of the weft-end threads is applicable to looms having an always stationair)l magazine as well as to one having a detachablo magaxinc.
